Tonight on Constantine we get to see John Constantine (Matt Ryan) team up with Papa Midnight (Michael James Shaw)… but the thing the below trailer does not show is we also get the first appearance of Jim Corrigan (Emmett J. Scanlan) who is also known in the DC Comics world as The Spectre.
Now Corrigan won't be the Spectre yet. Here we just see him as a police detective caught in the middle of a case that involves things he can't explain… and of course Constantine. But the producers are said to have continuing plans for the character. So it will be interesting to see how they begin here.
